Silver-doped silver type zeolite develops strong photoluminescence (PL) by treatment such as heating. After heating the Ag type A zeolite at 400 ° C for 24 hours, the PL measurement immediately after cooling showed the possibility that the site of the Ag ion after cluster disintegration in the zeolite cage was changed. Therefore, in order to observe the behavior of Ag under conditions similar to those at that time, XAFS and PL measurement were performed.
